Full impact of laboratory information system requires direct use by clinical staff: cluster randomized controlled trial
Open accessAbstract
OBJECTIVE: To evaluate the time to communicate laboratory results to health centers (HCs) between the e-Chasqui web-based information system and the pre-existing paper-based system. METHODS: Cluster randomized controlled trial in 78 HCs in Peru. In the intervention group, 12 HCs had web access to results via e-Chasqui (point-of-care HCs) and forwarded results to 17 peripheral HCs. In the control group, 22 point-of-care HCs received paper results directly and forwarded them to 27 peripheral HCs. Baseline data were collected for 15 months. Post-randomization data were collected for at least 2 years. Comparisons were made between intervention and control groups, stratified by point-of-care versus peripheral HCs. RESULTS: For point-of-care HCs, the intervention group took less time to receive drug susceptibility tests (DSTs) (median 9 vs 16 days, p<0.001) and culture results (4 vs 8 days, p<0.001) and had a lower proportion of 'late' DSTs taking >60 days to arrive (p<0.001) than the control. For peripheral HCs, the intervention group had similar communication times for DST (median 22 vs 19 days, p=0.30) and culture (10 vs 9 days, p=0.10) results, as well as proportion of 'late' DSTs (p=0.57) compared with the control. CONCLUSIONS: Only point-of-care HCs with direct access to the e-Chasqui information system had reduced communication times and fewer results with delays of >2 months. Peripheral HCs had no benefits from the system. This suggests that health establishments should have point-of-care access to reap the benefits of electronic laboratory reporting.

Although in a systematic review published in 1997 most studies of picture archiving and communication systems were found to cite the benefits of such systems, evidence of improvements in health outcomes, efficiency or costs was nil.

The Introduction and Discussion address laboratory-result reporting and the e-Chasqui system, not picture archiving and communication systems. Searches for PACS, a 1997 systematic review, and the claimed absence of evidence on health outcomes, efficiency, or costs found no passage addressing that claim in our copy. (LLM, conf=0.76)
Experimental — accuracy not yet measuredThere appeared to be no convincing proof that digital X-ray images were at least as good as conventional X-ray films in terms of diagnostic accuracy.

The Outcomes and Laboratory RDT sections assess how quickly tuberculosis culture and drug-susceptibility results reached health centers, not the diagnostic accuracy of X-ray images. Searches for digital X-rays, conventional film, and diagnostic accuracy found no passage addressing the claim. Page numbers were not provided for these passages. (LLM, conf=0.78)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
